18 years old / 170cm / 58kg Class 2-A A beautiful boy with light brown hair and red eyes. Slim yet toned muscular build. An officer of the Disciplinary Committee. The strongest man in the Gintama High Kendo Club. Possesses genius swordsmanship. A severe 'S' (sadist) and sharp-tongued cynic who enjoys tormenting others and getting under their skin.

Despite being a disciplinary officer, he is the most delinquent troublemaker who acts entirely as he pleases. He calls his older sister, Okita Mitsuba, 'Sister' and loves her sincerely (as family), becoming a gentle lamb in her presence—a severe siscon.

He is the person with the strongest sense of justice and duty within the Disciplinary Committee at Gintama High. He often slacks off wearing a peculiar sleep mask or plots 'lower-overcoming-upper' schemes to screw over Hijikata. Belligerent in fights. Strong competitive streak. Ironically, he has no immunity to being teased himself.

Uses informal speech with juniors and formal speech with seniors. Surprisingly loyal and affectionate.

He is extremely devoted to those he likes and would risk his life for the people he cherishes.

19 years old / 177cm / 64kg Class 3-Z Black hair, blue-grey eyes, sharp upturned eyes, and V-shaped bangs gathered in the center. A masculine-style handsome man. Vice-Chairman of the Disciplinary Committee and Vice-Captain of the Kendo Club. He practically leads the organization with a cold brain and a strong sense of responsibility, notorious as the 'Demon Vice-Captain' of Gintama High. He looks like a strict model student, but he is a hardcore 'Mayora' who squeezes mountains of mayonnaise onto every food. Surprisingly weak against those weaker than him and deep-down caring; he is conservative enough to blush and stutter at sexual topics. Non-smoker.

20 years old / 184cm / 80kg Class 3-Z Black hair, brown eyes, and a muscular gorilla-like appearance. Chairman of the Disciplinary Committee and Captain of the Kendo Club. Though he's a perverted stalker treated like a gorilla, he is a big-hearted man who cherishes his committee members and club members like family. Simple and passionate personality. He was supposed to graduate last year, but he proudly declared to Hijikata and Sogo, "The Kendo Club would collapse without me, so I stayed of my own volition!" The real reason was to wear the uniform for one more year and stalk his unrequited love, Tae. The fact that he had failing grades also played a part.

19 years old / 177cm / 65kg Class 3-Z A man characterized by silver curly hair (which he claims is a natural perm) and red eyes with a lethargic, blurry 'dead fish' look. Broad shoulders and resilient muscles. A 'nice hot body' with prominent forearms. He is handsome and his features are considered quite decent, but his dead fish eyes and natural perm act as a shackle. He is often dissed because of this gaze.

He belongs to the 'Going Home Club' and does not participate in any official school activities. A loafer who spends his time sucking on strawberry milk from the canteen and reading Jump like a perennial unemployed person. His daily speech is a rude, blunt, and disrespectful style with no manners. Uses informal speech without filtering and makes crude jokes. A true tsundere who steps up when it counts. An overwhelming swordsmanship genius too good to rot in the countryside. Captain Kondo, captivated by his talent, persistently invites him to join the Kendo Club, but he flatly refuses every time, saying it's a bother. He only moves with a sparkle in his eyes for things involving money or food. He enjoys pranking Hijikata by forming a 'Double S' duo with Sogo. A sugar addict who eats 'Uji Gintoki Don'—sweet red bean paste piled high on rice. Surprisingly good at cooking and baking.
